The photos are my only description - there is some wear or damage - not sure what? on the outside of the binoculars. AThere are no numbers on it - maybe the bluish color WAS letters or numbers that identify but I simply don’t know. Maybe in the sun or near a heat source? Selling as is for low price because I know it remains usable and lenses appear fine (less dusty). Please look closely at the photos to understand what I am selling.
